<p>webpack中的插件，就是对webpack现有功能的各种扩展，比如打包优化，文件压缩等等。</p>
<h2 id="loader和plugin区别"><a href="#loader和plugin区别" class="headerlink" title="loader和plugin区别"></a>loader和plugin区别</h2><p>loader主要用于转换某些类型的模块，它是一个转换器。</p>
<p>lugin是插件，它是对webpack本身的扩展，是一个扩展器。</p>
<h2 id="plugin的使用过程"><a href="#plugin的使用过程" class="headerlink" title="plugin的使用过程"></a>plugin的使用过程</h2><p>步骤一：通过npm安装需要使用的plugins(某些webpack已经内置的插件不需要安装)</p>
<p>步骤二：在webpack.config.js中的plugins中配置插件。</p>
<h2 id="添加版权的Plugin"><a href="#添加版权的Plugin" class="headerlink" title="添加版权的Plugin"></a>添加版权的Plugin</h2><p>该插件名字叫<strong>BannerPlugin</strong>，属于webpack自带的插件。</p>
<p>修改<code>webpac-config.js</code>配置文件</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610211709.png" alt="image-20200610211708354"></p>
<p>然后重新打包<code>npm run build</code>。查看打包的文件bundle.js。成功在头部加上版权信息</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610212043.png" alt="image-20200610212042026"></p>
<h2 id="打包html的plugin"><a href="#打包html的plugin" class="headerlink" title="打包html的plugin"></a>打包html的plugin</h2><p>目前，我们的index.html文件是存放在项目的根目录下的。</p>
<p>我们知道，在真实发布项目时，发布的是dist文件夹中的内容，但是dist文件夹中如果没有index.html文件，那么打包的js等文件也就没有意义了。</p>
<p>所以，我们需要将index.html文件打包到dist文件夹中，这个时候就可以使用<strong>HtmlWebpackPlugin</strong>插件</p>
<p>HtmlWebpackPlugin插件可以为我们做这些事情：</p>
<ul>
<li><p>自动生成一个index.html文件(可以指定模板来生成)</p>
</li>
<li><p>将打包的js文件，自动通过script标签插入到body中</p>
</li>
</ul>
<p>安装指定版本的<code>npm install html-webpack-plugin@3.2.0 --save-dev</code></p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610212714.png" alt="image-20200610212712905"></p>
<p>编写配置文件<code>webpack-config.js</code></p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610213029.png" alt="image-20200610213028148"></p>
<p>然后重新打包<code>npm run build</code>。查看打包的文件dist目录下的index.html。发现它将打包的js文件，自动通过script标签插入到body中。</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610213200.png" alt="image-20200610213159345"></p>
<p>但是我们使用了vue所以需要被vue挂载的元素<code>&lt;div id = &#39;app&#39;&gt;&lt;/div&gt;</code>我们将根目录下的index.html中的div删除。在通过template选择模板</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610213443.png" alt="image-20200610213441815"></p>
<p>在配置<code>webpack-config.js</code>文件</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610213541.png" alt="image-20200610213540013"></p>
<p>以根目录下的index.html为模板生成dist目录下的index.html文件，并自动打包的js文件，自动通过script标签插入到body中。</p>
<p>重新<code>npm run build</code>查看dist目录下的index.html</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610213716.png" alt="image-20200610213713490"></p>
<p>此时生成了我们想要的div，同时也自动引入了我们打包的js文件。但是由于我们先前为了能使根目录下的index.html能导入dist中的图片，在webpack配置文件中对output中添加的publicPath属性值为’dist/‘。所以我们要将其删除或者注释</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610214010.png" alt="image-20200610214008718"></p>
<p>重新<code>npm run build</code>查看dist目录下的index.html。并查看效果</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610214130.png" alt="image-20200610214129408"></p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610214151.png" alt="image-20200610214149639"></p>
<h2 id="js压缩的plugin"><a href="#js压缩的plugin" class="headerlink" title="js压缩的plugin"></a>js压缩的plugin</h2><p>在项目发布之前，我们必然需要对js等文件进行压缩处理。这里，我们就对打包的js文件进行压缩</p>
<p>我们使用一个第三方的插件uglifyjs-webpack-plugin，并且版本号指定1.1.1，和CLI2保持一致</p>
<p><code>npm install uglifyjs-webpack-plugin@1.1.1 --save-dev</code></p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610214338.png" alt="image-20200610214337285"></p>
<p>修改<code>webpack.config.js</code>文件，使用插件</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610214438.png" alt="image-20200610214436697"></p>
<p><strong>压缩js，把空格注释删除。所以上文中的版权声明消失了</strong></p>
<p>重新<code>npm run build</code>查看dist目录下的bundle.js。压缩成功</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610214554.png" alt="image-20200610214552552"></p>
<h2 id="搭建本地服务器"><a href="#搭建本地服务器" class="headerlink" title="搭建本地服务器"></a>搭建本地服务器</h2><p>webpack提供了一个可选的本地开发服务器，这个本地服务器基于node.js搭建，内部使用express框架，可以实现我们想要的让浏览器自动刷新显示我们修改后的结果。</p>
<p>不过它是一个单独的模块，在webpack中使用之前需要先安装它<code>npm install --save-dev webpack-dev-server@2.9.1</code></p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610214843.png" alt="image-20200610214841984"></p>
<p>devserver也是作为webpack中的一个选项，选项本身可以设置如下属性：</p>
<ul>
<li><p>contentBase：为哪一个文件夹提供本地服务，默认是根文件夹，我们这里要填写./dist</p>
</li>
<li><p>port：端口号</p>
</li>
<li><p>inline：页面实时刷新</p>
</li>
<li><p>historyApiFallback：在SPA页面中，依赖HTML5的history模式</p>
</li>
</ul>
<p><code>webpack.config.js</code>文件配置修改如下</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610215059.png" alt="image-20200610215057687"></p>
<p><strong>我们可以再配置另外一个scripts：dev。–open参数表示直接打开浏览器</strong></p>
<p><strong>dev与webpack-dev-server发生映射，并且通过–open参数，运行后直接打开浏览器</strong></p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610215259.png" alt="image-20200610215258287"></p>
<p>运行<code>npm run dev</code>查看效果</p>

<p>这时候修改main.js文件查看是否是实时更新。实时更新成功！</p>

<h2 id="Webpack配置文件的分离"><a href="#Webpack配置文件的分离" class="headerlink" title="Webpack配置文件的分离"></a>Webpack配置文件的分离</h2><h3 id="单个配置文件所造成的问题"><a href="#单个配置文件所造成的问题" class="headerlink" title="单个配置文件所造成的问题"></a>单个配置文件所造成的问题</h3><p>随着我们业务逻辑的增多，图片、字体、css、ES6以及CSS预处理器和后处理器逐渐的加入到我们的项目中来，进而导致配置文件的增多，使得配置文件书写起来比较繁琐，更严重者（书写特定文件的位置会出现错误）。更由于项目中不同的生产环境和开发环境的配置，使得配置文件变得更加糟糕。</p>
<p>使用单个的配置文件会影响到任务的可重用性，随着项目需求的增长，我们必须要找到更有效地管理配置文件的方法。</p>
<h3 id="分离配置文件"><a href="#分离配置文件" class="headerlink" title="分离配置文件"></a>分离配置文件</h3><p>我们在根目录下创建build文件夹。创建<code>base.config.js</code>的webpack基础配置文件。将我们之前编写好的<code>webpack.config.js</code>文件复制到这里。并进行修改。</p>
<p><strong>删除了对打包后的js文件的压缩插件，和本地服务器的配置</strong></p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/github/images/20200610221008.png" alt="image-20200610221007557"></p>
<p>接着创建一份开发时使用webpack的配置文件<code>dev.config.js</code>在基础配置文件的基础上只需要添加使用本地服务器功能即可</p>
<p>同时我们需要导入插件<code>webpack-merge</code>将我们的<code>base.config.js</code>与<code>dev.config.js</code>合并<code>npm install webpack-merge --save-dev</code></p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610223138.png" alt="image-20200610223137028"></p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/github/images/20200610222643.png" alt="image-20200610222642208"></p>
<p>同理配置生产时使用的webpack配置文件<code>prod.config.js</code>在基础配置文件的基础上只需要添加使用压缩js插件即可。并将其合并</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610223319.png" alt="image-20200610223318447"></p>
<h3 id="配置package-json"><a href="#配置package-json" class="headerlink" title="配置package.json"></a>配置package.json</h3><p>配置文件完成分离之后，我们需要配置package.json的script脚本。通过<code>--config</code>指定运行指定的webpack配置文件</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610223534.png" alt="image-20200610223533005"></p>
<p>测试使用<code>npm run dev</code>运行我们配置的webpack开发时的配置文件。</p>
<p><img src= "https://gitee.com/kylincw/images/raw/master/loading.gif" data-lazy-src="https://qiniu.codekylin.cn/img/20200610223726.png" alt="image-20200610223725280"></p>
<p>成功启动了配置好的本地服务器。</p>
